Research On Generation Technology Of Integrated Imaging 3D Display Content Based On Multi-viewpoint Acquisition

As a kind of three-dimensional display technology,the integral imaging system has the advantages of good continuity,full parallax and no visual fatigue.However,the traditional integrated imaging system uses a microlens array to obtain 3D scene information,and the resolution of the collected stereo image is low,and the resulting integrated imaging 3D display effect is poor.This article mainly studies the use of multi-viewpoint acquisition methods,including axial viewpoints.There are three methods of acquisition,off-axis viewpoint acquisition and binocular vision acquisition to generate a three-dimensional image array for three-dimensional reproduction.The traditional integral imaging system acquires a depth map by using a microlens array to acquire a stereo element image.Due to the size limitation,the resolution of the acquired element image is very low,and the quality of the acquired depth map is poor.This paper proposes the acquisition of high-quality depth images based on axial viewpoint and off-axis viewpoint.The proposed method uses a single camera to perform axial and off-axis shooting.According to the parameters set by the acquisition mode and the proportional relationship between the distances of the corresponding points between the collected element images,the coordinates of the image points of the same name in the element images of the three-dimensional object points are calculated;Calculate the depth of the point based on the minimum error of the color value of the corresponding points.The acquisition method studied in this paper only needs a camera to move along the optical axis.The movement is simple and high-resolution element images can be acquired.The longitudinal parallax information of the element images is fully utilized and accurate depth maps can be extracted effectively.The depth map and the color map are subjected to a pixel mapping method to obtain a three-dimensional image array for three-dimensional display.When studying the generation technology of binocular vision acquisition integrated imaging 3D display content,in order to obtain high-quality depth images,this paper proposes a depth map acquisition method based on an improved quantum genetic algorithm.The depth image is obtained by using the left and right disparity of the plane,and the improved quantum genetic algorithm is used for segmentation,and then the multi-threshold segmentation image is subjected to stereo matching based on the filter window,and the corresponding disparity map can be obtained.Finally,the disparity map is converted into a depth map,and after the depth map is obtained,the corresponding three-dimensional image array is obtained by the pixel mapping method for three-dimensional light field reproduction.Using the improved quantum genetic algorithm to segment images can effectively increase the convergence speed and obtain high-quality threshold segmentation images,thereby obtaining accurate depth images,and providing a feasible method for acquiring stereo image arrays.
